A recombination-resistant genome for live attenuated and stable PEDV vaccines by engineering the transcriptional regulatory sequences.

Coronaviruses are important pathogens of humans and animals, and vaccine developments against them are imperative. Due to the ability to induce broad and prolonged protective immunity and the convenient administration routes, live attenuated vaccines (LAVs) are promising arms for controlling the deadly coronavirus infections. However, potential recombination events between vaccine and field strains raise a safety concern for LAVs.

Treatment Efficacy and Technical Advantages of Temporary Spinal Nerve Root Stimulation Compared to Traditional Spinal Cord Stimulation for Postherpetic Neuralgia.

Background: Postherpetic neuralgia (PHN) is a common complication after herpes zoster infection. While conventional dorsal column temporary spinal cord stimulation (tSCS) has been shown as an effective treatment option for this pain condition, recent data suggests ipsilateral temporary spinal nerve root stimulation (tSNRS) as a safe alternative for treating PHN. However, there is no direct clinical comparison between the newer tSNRS and the traditional tSCS.

In vitro activity and adaptation strategies of eravacycline in clinical Enterococcus faecium isolates from China.

Eravacycline (Erava) is a synthetic fluorocycline with potent antimicrobial activity against a wide range of Gram-positive bacteria. This study aimed to investigate the in vitro antimicrobial activity and resistance mechanism of Erava in clinical E. faecium isolates from China.

Antibacterial activities and action mode of anti-hyperlipidemic lomitapide against Staphylococcus aureus.

Background: The increasing emergence of multidrug-resistant Gram-positive bacterial infections necessitates new antibacterial agents with novel mechanisms of action that can be used to treat these infections. Lomitapide has been approved by FDA for years in reducing levels of low-density lipoprotein (LDL) in cases of familial hypercholesterolemia, whereas the antibacterial effect of lomitapide remains elusive. In this study, the inhibitory activities of lomitapide against Gram-positive bacteria were the first time explored.
